Original Abstract

In this paper, we present the quantitative study of the effects of the selected most important transceiver imperfections on the performance of digital pre-distortion linearizers. Starting from the power amplifier model identification based on the measured data captured using the low-cost software defined radio platform, we evaluate the performance in term of out-of-band signal emissions at the power amplifier output for the case of typical representative of signals envisaged for fifth generation (5G) of mobile communication systems. The results are presented for the values of imperfections (IQ imbalances, DC offset) swept within the range of values corresponding to commercially available wireless front-ends. We highlight the fact that the front-end imperfections can significantly affect the influence of pre-distorters.
